AD630 as Lock In Amplifier

I am using an AD630 as a lock in amplifer and I have a question about input waveform.  Most lock in amplifiers use a sine wave for the carrier frequency and I am wondering if I were to use a triangle waveform instead.   Would this change the responcs of the demodulator?

 

Thanks!
